Bond veteran Ken Leech, former chief investment officer at Western Asset Management, entered a guilty plea on Friday, admitting to a single count of obstructing a Securities and Exchange Commission probe. The plea came just days before a federal trial in New York’s Southern District was slated to begin. Prosecutors had originally charged him with investment adviser and securities fraud.

The obstruction charge carries a maximum five‑year sentence, far lower than the 20‑year penalties attached to the fraud counts. Investigators say Leech orchestrated a cherry‑picking scheme from January 2021 through October 2023, assigning roughly $600 million in gains to favored clients while shifting an equal amount of losses to others. The manipulation relied on delaying trade allocations until performance was known.

Lawyers for Leech declined comment, and the Justice Department has not responded. The case underscores heightened regulator scrutiny of fixed‑income firms that manage large institutional portfolios. By pleading to obstruction, Leech avoids a trial that could have exposed broader compliance failures at Western Asset, leaving investors to reassess risk controls in bond‑trading desks and their compensation structures for future operations.
